Because Grealish was £100m, Son is worth £125m' - Waddle surprised Man Utd and Man City aren't in for Spurs star

The former Tottenham winger is a big fan of the South Korean, who has committed to a new long-term contract in north London

With Jack Grealish costing a British record £100 million ($138m) when joining Manchester City in the current transfer window, Tottenham forward Son Heung-min is now worth at least £125m ($173m), says Chris Waddle.

Big-money deals have been completed and speculated on this summer, with Harry Kane expected to generate an eye-watering fee before eventually seeing the exits blocked at Spurs.

His club colleague, South Korea international Son, is yet to attract that kind of interest but Waddle believes it is only a matter of time before the 29-year-old's true value - on and off the field - is recognised by the European elite
